About Us

About ESI Technologies Group

ESI Technologies Group is the foremost supplier of Process Equipment & Engineering Solutions for the Biotech, Pharmaceutical, Chemical, Semi-Conductor, and Food & Beverage industries in Ireland and the UK. ESI also caters to the Nuclear/Power and Oil & Gas sectors in the UK.

Our supply partners include renowned blue chip companies such as Emerson, Flowserve, Crane, ITT, Millipore, Alfa Laval and Parker, along with privately owned companies like Habonim, EBRO, Amazon, and Continental Disc Corporation.

Since its establishment in 1919, ESI has maintained a rich history and sustained growth in both Ireland and the UK.

Operating under the motto “More than Equipment Suppliers…Solution Providers!” we have built our offerings on the commitment and expertise of our personnel. The greatest asset lies in our knowledge and our core Engineers at ESI collectively possess over 300 years of experience in Process Applications, specifically in Valves, Pumps, Control Systems, Safety Measures, Aseptic Processes, and Instrumentation.

We are not solely reliant on manufacturers for support, as all our staff undergo factory training. This enables us to provide quick turnaround times for quotes and a customer-centric rapid response. Consequently, all knowledge remains in-house, and ESI handles the sizing and selection of equipment. This approach allows us to cultivate long-term strategic perspectives and offer comprehensive process solutions, fostering enduring relationships with our clients. Furthermore, our Engineering team collaborates closely with on-site engineers, ensuring competitive technical solutions and the ability to suggest and source alternatives based on their vast experience.

When combined with our comprehensive Service Division, staffed by product-trained engineers specialising in repair, installation, and commissioning, we possess extensive expertise in effectively delivering large projects since our inception over 100 years ago.
